A rabbi told me that ancient Kabbalistic texts suggest that the Gardenof Eden is located in the center of the earth and the earth is hollow.(When Adam and Eve were expelled from the Garden of Eden, they wereexpelled to the outer earth.) Not only this, but the inner earth isnot Euclidean as we would normally picture it. In layman's terms, "Theinner earth is in another dimension."

As we know, this sentiment goes against the modern science.

But let's suppose that the earth were hollow and the inner earth were"in another dimension". What would the possible topologies of such aninner earth look like?
